Oculus Working on Headset-Mounted Camera With Possible Gesture Controls

VRFocus - It has been revealed that Oculus VR, the company behind the Oculus Rift virtual reality (VR) headset, is working on a second camera for the headset on top of the one included in the second developer kit (DK2). The proposed addition would be fitted to the headset itself, facing outwards as opposed to the first camera that sits in front of users to track the position of the device and replicate physical head movements in-game.

You are right but since a lot of first person games are build around holding something (an axe, a gun, a crowbar) I figure this will be more important, In the future they should tackle other types of motion attachments like gloves and I dunno something you strap around your waste.
